Dwight Tiendalli joined Swansea City from Twente in summer 2012. He signed a 1-year contract at the Welsh club as defensive cover for the first choice left back Neil Taylor who sustained an ankle injury ruling him out for the whole 2012-13 season.

After leaving the Swans at the end of his contract in June 2013, he rejoined the club in just two months later, penning a three-year deal until 2016. Tiendalli moved to Middlesbrough in the end of March 2015 for a loan-deal until the end of the season.

At the 1st of September 2015 Swansea City dissolved the contract of Tiendalli, so the player was transfer free again and looking for a new opportunity. Finally in summer 2017 the former Dutch international managed to find himself a new club. League One Oxford United offered the defender a chance to play in the 2017-18 season for the club. Tiendalli played 13 matches in his League One season before his contract expired.
